Apple drops first betas of macOS 10.13.4 and tvOS 11.3

Developers received a hot new batch of updates from Apple today that bring a host of new features to Macs and the Apple TV.

tvOS 11.3 beta 1 and macOS 10.13.4 beta 1 are now available for registered developers, along with a new XCode 9.3 build and iOS 11.3.

Registered developers can grab the new beta builds directly from Apple’s online developer portal. You can install macOS 10.13.4 beta 1 through the Mac App Store’s update section once you add the proper profile to your Mac.

While iOS 11.3 is packed with a ton of outward facing features, tvOS 11.3 and macOS 10.13.4 both appear to focus more on performance fixes and under the hood issues.

Release notes for macOS 10.13.4 don’t mention any big changes. One of the biggest additions is iCloud support for Messages. That feature was just added in iOS 11.3 beta 1 but it’s unclear if it’s ready for the Mac yet.

We’ll let you know if we find any notable additions once we get the new software running on your devices.
